Air pumps

I have just bought an air pump (Sera 110) was wondering how important
the siting of it was. There are lots of don't site it here on the
instuctions ( http://www.sidtech.co.uk/iu/soup74240143411.jpg ). I can
see the ones where you don't site it directly above/below the aquarium
and not to site it on a sloping shelf but there are also instructions to
not site it so it pumps air up the airline and then under the water
indeed the only place you can site it is slightly above water level but
a distance to the side. Best place for us is the pump at the bottom
level of the tank then the air line running up to the tank top then down
again under the water, the air line goes slightly above the level of the
tank to avoid siphoning if the pump fails, it also has a one way valve
in the air line so water shouldn't be able to flow back down the line.

Higher is better just in case the check valve fails.....
